A NH Electric EP5 30-2170 is being advertised (used) as "Proto".   As there is no 30-2170 in the online MTH catalog , it must therefore be a 30-2170-1.  May I assume then, that as a -1 it is a PS2 engine?   I don't think I'd want it if it's a PS1.

Clearly, it's a plain Protosound locomotive, it is NOT PS/2.

If you look at it on the MTH site, you can also open the user's manual and clearly see it's not PS/2.

In the beginning with Proto Sound  a -1 meant ProtoSound.  A -0 meant Horn/Whistle board and DCRU.  Remember PS was a Command control of sorts, via bell/whistle and throttle setting.

Once PS-1 was replaced by PS-2 and DCS, -1 is Command and -0 is Conventional of some sort, usually Locosounds.

Anything up to 1999 and even some in 2000 where Protosound.  Later in 2000 and up Proto Sound 2.  Always check instructions and such.  There were some miss marked in that transition period.

Thank you for the clarification.  I only adopted DCS a couple of years ago and still fuzzy on the designations.  Always on the lookout for NH road name engines, but not interested in anything less than PS2.

Just a follow up question to this post of mine from last month:   So a -1 Proto from the early era (before 2000) , would require CONVENTIONAL control (variable AC), and would not recognize a DCS speed control signal, correct?

I frequently see comments on the Forum from people who are reluctant to buy PS-1. As someone who owns and runs quite a few PS-1 locomotives (conventional), that doesn't seem justified to me. Mine have been running trouble-free for more than twenty years. They run smoothly at low speeds, especially after break-in, even without speed control. Just replace the battery with a BCR. The New Haven EP-5 in this video is an MTH Premier with PS-1 from the first run around 2000. As a passenger engine, I run it mostly at mainline speeds, but it also runs well at very low speeds. Just my opinion

Quick answer, yes, it's only conventional control.
